I forget where I read it (I think FiveThirtyEight), but Cruz is actually in a much bigger hole than it appears. Most of his best states (including TX) are proportional, whereas most of his worst states are winner take all.
This is a great point. If Trump continues to win the winner take all states, and does even half way decently in the proportional states, it's all over. Cruz taking third in a state in which he should have done well is an indication of just how much weaker he is than he'd like us to believe.
